hi all got a 2000 1.0 and its just aquired a slight judder just before it starts to idle any help much appriciated

when you start it up does it judder then idle then judder then if you rev it stops then starts to judder again? also does it do it sometimes when you are driving then you come to a stop say at the lights does it start to judder then while your stationary?
if so then mine does that i think its idle control valve im gunna clean mine when snow goes.
hope this helps

it doesnt realy judder at any other time apart from that second just before its idle once its idle its ok
